HINGE.

SPECIFICATION forming part of Letters Patent No. 487,476, dated December 6, 1892.

Application filed December 31, 1890. Renewed May 21, 1892. Serial No. 433,792. (No model.)

To all whom it may concern:

Be it known that we, FRIEDRICH AUGUST HERMANN FAULHABER and CHR-ISTOPH FRIEDRICH KOCH, subjects of the King of Niirtemberg, German Empire, and residents of the city of Schwabisch Hall, in the Kingdom of Wiirteniberg, German Empire, have invented certain new and useful Improvements in Door-Hinges, of which the following is a specification.

This invention relates to door-hinges, and especially to pivot-hinges for doors that open in both directions. Vith the pivot-hingesin use heretofore considerable difficulty was experienced in removing or replacing the door Without mutilating or defacing the frame in which the door was hung or the door itself.

The object of our invention is to provide a new and improved pivot-hinge, which is so constructed that the door can readily be hung or removed.

The invention consists in the construction and combination of parts and details, as will be fully set forth hereinafter, and pointed out in the claim.

In the accompanying drawings, Figure 1 is an elevation of a door provided with our improved pivot-hingcs adapted to slide on the door from the rear edge, parts being broken out and others being in section. Fig. 2is an elevation of a door provided with our improved pivot-hinges adapted to be placed lat erally on the door, parts being broken out and othersbeing in section. Fig. 3 is a vertical longitudinal sectional view, on an enlarged scale, of our improved construction of pivot'hinges shown in Fig. 1. Fig. 4 is aplan view of the same. Fig. 5 is an end view, parts being in section. Fig. 6 is an enlarged face View of the pivot-hinge shown in Fig. 2, parts being in section. Fig. 7 is a plan view of the same. Fig. Sis a vertical longitudinal sectional view. Fig. 9 is an elevation of a door provided with a construction of ourimproved pivot-hinge wherein the pivot is fastened to the door-casing. Fig. 10 is an enlarged 1ongitudinal sectional view of our improved pivot-hinge shown in Fig. 9. Fig. 11 is a vertical transverse sectional view of the bottom plate, and Fig. 12 is a view of the under side of the upper plate.

Similar letters of reference indicate corresponding parts.

The pivot 0, adapted to turn in the socket 0, projects from the horizontal dovetailed arm of an angle-iron B. The angle-iron A, placed in a suitable recess at the corner of the door T, is provided in its horizontal arm with a dovetail recess, as shown in dotted lines in Fig. 4, adapted to receive the dovetail horizontal arm of the angle-iron B. Said horizontal arm is slid in said dovetail recess, the vertical arm of the angle-iron B passing into vertical recesses in the outer surface of the vertical arm of the angle-iron A. By means of screws 2) the angle-iron B is held in place in the recesses of the angle-iron A, and screws a serve to hold the angle-iron A on the corner of the door. To remove the door, the screws 12 b are l0osened,when the door can be pulled out in the direction of the length of the horizontal arm of the angle-irons A and B. The sockets C are fastened in suitable recesses in the top and bottom cross pieces of the door-frame, as shown in Fig. 1.

In the construction shown in Figs. 2, 6, 7, and 8 the angle-iron A is fastened in a recess in the side or face of the door, and the angleiron B slides laterally into the same, the angle-iron A being fastened by the screws a and the angle-iron B being fastened by the screws 1). To remove the door, the screws 1) are loosened and the door at the hinged endis moved 0 utward laterally, so as to withdraw the angle-iron A from the angle-iron B, carrying the pivot C, that rotates in the socket O.

In the construction shown in Figs. 9 to 12 the pivot is not held on the door, but on the casing. Said pivot 0 projects downwardly from the wedge-shaped dovetailed plate B placed into a wedge-shaped dovetailed recess A in the underside of the plate A which is fastened by screws 01, in the bottom surface of the top cross-piece of the door-casing or in the upper surface of the bottom cross-piece. The recess A is longer than the sliding piece B so as to adapt said piece to slide in said recesses. The plate D is fastened by means of screws d on the top or bottom edge of the door and is provided at one end with the aperture through which the pivot O can pass. A screw 1) serves for holding the sliding piece B in place in the guide or groove A of the plate A To remove the door, the same is first opened, so as to give access to the screw b which is loosened, and then the door is removed in such a direction as to cause the wedge-shaped dovetailed piece B to slide lengthwise, as indicated by the arrow in Fig. 12 in the grooveA As the said wedge-shaped dovetail piece B is now in the widerend of the groove A it can easily be moved out of said groove, thus permitting the detaching of the door.

Having thus described our invention, we claim as new and desire to secure by Letters Patent-- The combination, in a door-hinge, of an an-
